Just got some heads last night
 

Finnally finished up the heads for my 454. I have 10+ hours into porting and combustion chamber work. And my machinest has 5+ hours into 4 cut performance valve job and surfaced 0.035 of them. We CC'ed them last night to 116.5 They have a new set of Crane springs in them and PC seals. Rag's

They started life as 99 502 EFI heads.

Exhausting work! :D Rag's

Last one for today! :D Rag's

Nice.
When my heads where worked over last year, the builder filled the exhaust port crossovers with alum and then blended it with the rest of the chamber. (That would be the hole in picture #3) Not sure if it helped any, but looked good in theory. Don't need no stinkin carb preheat on no race boat! :)

Hey Rag,I did heads for 20 years,if those intakes are the Heavy tuliped valves ,i would put them in my anchor locker,they are spring killers. buy some super dutys or anything else. tripps

They look pretty but how do they flow?

Buy Tuliped do you mean undercut from the steam to the body of the valve? Because these are not under cut I think the stain from use does kinda make them look that way in the photo. The valves are the stock Eatons that came in them as they were Mercruser Magnum heads. If I am still missing your point fell fre to chime in agian as I appreciate any and all imput. Rag's

Marty good question, unfortionitly I dont have a good answer, besides alot better thatn the small valve penut port heads that were on the motor. My machine shop guy was leaving to vegas for 3 weeks and I did not want to wait tell after he gets back to take them to his freind that has a flow bench. Rag's :D

Hey Rag,I think eatons were the least expensive valve ever made,do your self a favor ,and your motor and put some H.D. manelys,or Ferreras in there. anybody else ? tripps

TTT
 

no other thoughts or coments or ridacules?

IF ITS BLOWN YOU NEED DIFFERNT ANGLES AND ANYWAY PLEASE USE SEVERE DUTY AT LEAST ,IT WILL SAVE YOU A TON LATER ,,,EATONS ARE MADE FROM RE-BAR :D :D
